1 == MediaWiki 1.30 ==
2
3 THIS IS NOT A RELEASE YET
4
5 MediaWiki 1.30 is an alpha-quality branch and is not recommended for use in
6 production.
7
8 === MySQL version requirement in 1.30 ===
9 As of 1.30, MediaWiki now requires MySQL 5.5.8 or higher (see Compatibility
10 section).
11
12 === Configuration changes in 1.30 ===
13 * The "C.UTF-8" locale should be used for $wgShellLocale, if available, to avoid
14 unexpected behavior when code uses locale-sensitive string comparisons. For
15 example, the Scribunto extension considers "bar" < "Foo" in most locales
16 since it ignores case.
17 * $wgShellLocale now affects LC_ALL rather than only LC_CTYPE. See
18 documentation of $wgShellLocale for details.
19 * $wgShellLocale is now applied for all requests. wfInitShellLocale() is
20 deprecated and a no-op, as it is no longer needed.
21 * $wgJobClasses may now specify callback functions as an alternative to plain
22 class names. This is intended for extensions that want control over the
23 instantiation of their jobs, to allow for proper dependency injection.
24 * $wgResourceModules may now specify callback functions as an alternative
25 to plain class names, using the 'factory' key in the module description
26 array. This allows dependency injection to be used for ResourceLoader modules.
27 * $wgExceptionHooks has been removed.
28 * (T45547) $wgUsePigLatinVariant added (off by default).
29
30 === New features in 1.30 ===
31 * (T37247) Output from Parser::parse() will now be wrapped in a div with
32 class="mw-parser-output" by default. This may be changed or disabled using
33 ParserOptions::setWrapOutputClass().
34 * Added 'ChangeTagsAllowedAdd' hook, enabling extensions to allow software-
35 specific tags to be added by users.
36 * Added a 'ParserOptionsRegister' hook to allow extensions to register
37 additional parser options.
38 * (T45547) Included Pig Latin, a language game in English, as a
39 LanguageConverter variant. This allows English-speaking developers
40 to develop and test LanguageConverter more easily. Pig Latin can be
41 enabled by setting $wgUsePigLatinVariant to true.
42 * Added RecentChangesPurgeRows hook to allow extensions to purge data that
43 depends on the recentchanges table.
44 * Added JS config values wgDiffOldId/wgDiffNewId to the output of diff pages.
45
46 === Languages updated in 1.30 ===
47
48 * Support for kbp (Kabɩyɛ / Kabiyè) was added.
49 * Support for skr (Saraiki, سرائیکی) was added.
50
51 === External library changes in 1.30 ===

56

60
61 ==== Removed and replaced external libraries ====
62 * …
63
64 === Bug fixes in 1.30 ===
65 * (T151633) Ordered list items use now Devanagari digits in Nepalese
66 (thanks to Sfic)
67
68 === Action API changes in 1.30 ===
69 * (T37247) action=parse output will be wrapped in a div with
70 class="mw-parser-output" by default. This may be changed or disabled using
71 the new 'wrapoutputclass' parameter.
72 * When errorformat is not 'bc', abort reasons from action=login will be
73 formatted as specified by the error formatter parameters.
74 * action=compare can now handle arbitrary text, deleted revisions, and
75 returning users and edit comments.
76 * (T164106) The 'rvdifftotext', 'rvdifftotextpst', 'rvdiffto',
77 'rvexpandtemplates', 'rvgeneratexml', 'rvparse', and 'rvprop=parsetree'
78 parameters to prop=revisions are deprecated, as are the similarly named
79 parameters to prop=deletedrevisions, list=allrevisions, and
80 list=alldeletedrevisions. Use action=compare, action=parse, or
81 action=expandtemplates instead.
82
83 === Action API internal changes in 1.30 ===
84 * ApiBase::getDescriptionMessage() and the "apihelp-*-description" messages are
85 deprecated. The existing message should be split between "apihelp-*-summary"
86 and "apihelp-*-extended-description".
87 * (T123931) Individual values of multi-valued parameters can now be marked as
88 deprecated.
89
90 === Languages updated in 1.30 ===
91 MediaWiki supports over 350 languages. Many localisations are updated
92 regularly. Below only new and removed languages are listed, as well as
93 changes to languages because of Phabricator reports.
94
95 * …
96
97 ==== Pig Latin added ====
98 * (T45547) Added Pig Latin, a made-up English variant (en-x-piglatin),
99 for easier variant development and testing. Disabled by default. It can be
100 enabled by setting $wgUsePigLatinVariant to true.
101
102 === Other changes in 1.30 ===
103 * The use of an associative array for $wgProxyList, where the IP address is in
104 the key instead of the value, is deprecated (e.g. [ '127.0.0.1' => 'value' ]).
105 Please convert these arrays to indexed/sequential ones (e.g. [ '127.0.0.1' ]).
106 * mw.user.bucket (deprecated in 1.23) was removed.
107 * LoadBalancer::getServerInfo() and LoadBalancer::setServerInfo() are
108 deprecated. There are no known callers.
109 * File::getStreamHeaders() was deprecated.
110 * MediaHandler::getStreamHeaders() was deprecated.
111 * Title::canTalk() was deprecated. The new Title::canHaveTalkPage() should be
112 used instead.
113 * MWNamespace::canTalk() was deprecated. The new MWNamespace::hasTalkNamespace()
114 should be used instead.
115 * The ExtractThumbParameters hook (deprecated in 1.21) was removed.
116 * The OutputPage::addParserOutputNoText and ::getHeadLinks methods (both
117 deprecated in 1.24) were removed.
118 * wfMemcKey() and wfGlobalCacheKey() were deprecated. BagOStuff::makeKey() and
119 BagOStuff::makeGlobalKey() should be used instead.
120 * (T146304) Preprocessor handling of LanguageConverter markup has been improved.
121 As a result of the new uniform handling, '-{' may need to be escaped
122 (for example, as '-<nowiki/>{') where it occurs inside template arguments
123 or wikilinks.
124 * (T163966) Page moves are now counted as edits for the purposes of
125 autopromotion, i.e., they increment the user_editcount field in the database.
126 * Two new hooks, LogEventsListLineEnding and NewPagesLineEnding, were added for
127 manipulating Special:Log and Special:NewPages lines.
128 * The OldChangesListRecentChangesLine, EnhancedChangesListModifyLineData,
129 PageHistoryLineEnding, ContributionsLineEnding and DeletedContributionsLineEnding
130 hooks have an additional parameter, for manipulating HTML data attributes of
131 RC/history lines. EnhancedChangesListModifyBlockLineData can do that via the
132 $data['attribs'] subarray.
133 * (T130632) The OutputPage::enableTOC() method was removed.
134 * WikiPage::getParserOutput() will now throw an exception if passed
135 ParserOptions that would pollute the parser cache. Callers should use
136 WikiPage::makeParserOptions() to create the ParserOptions object and only
137 change options that affect the parser cache key.
138 * Article::viewRedirect() is deprecated.
139 * DeprecatedGlobal no longer supports passing in a direct value, it requires a
140 callable factory function or a class name.
141 * The $parserMemc global, wfGetParserCacheStorage(), and ParserCache::singleton()
142 are all deprecated. The main ParserCache instance should be obtained from
143 MediaWikiServices instead. Access to the underlying BagOStuff is possible
144 through the new ParserCache::getCacheStorage() method.
145 * .mw-ui-constructive CSS class (deprecated in 1.27) was removed.
146
147 == Compatibility ==
148 MediaWiki 1.30 requires PHP 5.5.9 or later. There is experimental support for
149 HHVM 3.6.5 or later.
150
151 MySQL/MariaDB is the recommended DBMS. PostgreSQL or SQLite can also be used,
152 but support for them is somewhat less mature. There is experimental support for
153 Oracle and Microsoft SQL Server.
154
155 The supported versions are:
156
157 * MySQL 5.5.8 or later
158 * PostgreSQL 8.3 or later
159 * SQLite 3.3.7 or later
160 * Oracle 9.0.1 or later
161 * Microsoft SQL Server 2005 (9.00.1399)
162
163 == Upgrading ==
164 1.30 has several database changes since 1.29, and will not work without schema
165 updates. Note that due to changes to some very large tables like the revision
166 table, the schema update may take a long time (minutes on a medium sized site,
167 many hours on a large site).
168
169 Don't forget to always back up your database before upgrading!
170
171 See the file UPGRADE for more detailed upgrade instructions, including
172 important information when upgrading from versions prior to 1.11.
